Thermal Scale Formulas
Unlike distance or mass, thermal scale conversions require shifting zero-points (offsets) alongside ratio multipliers:
Celsius to Fahrenheit
°F = (°C × 9/5) + 32
Water freezes at $0^\circ\text{C}$ ($32^\circ\text{F}$) and boils at $100^\circ\text{C}$ ($212^\circ\text{F}$).
Absolute Zero (Kelvin)
K = °C + 273.15
Kelvin starts at absolute zero ($0\text{ K} = -273.15^\circ\text{C}$), the state where particle thermal motion ceases.
